Benthic Temperature Logs from the Gully MPA (2021-2022)

Fisheries and Oceans Canada provides benthic temperature logger data from two Vemco miniloggers deployed at approximately 300 meters depth in the Gully Marine Protected Area. The dataset covers the period from 2021 through 2022, capturing time-series measurements for underwater monitoring.

Use Cases

• Analyze benthic temperature time-series data from 2021-2022 to study seasonal thermal variations at 300m depth.
• Correlate temperature fluctuations from the Vemco miniloggers with broader marine ecosystem changes in the Gully MPA.
• Use the continuous logger data as environmental covariates for acoustic receiver range-testing analyses.

Strengths

• Data covers a two-year period (2021-2022), providing a continuous time-series for analysis.
• Measurements are from a specific, ecologically significant location: the Gully Marine Protected Area at ~300m depth.
• Data is provided in multiple accessible formats including CSV, FGDB/GDB, and ESRI REST services.

Limitations

• The dataset is limited to two sensor locations, offering limited spatial coverage within the MPA.
• Sample data and column definitions are unavailable, complicating initial data exploration and schema understanding.
• The dataset's size and total number of data points (rows) are unknown, making it difficult to assess computational requirements.
